Like most badids this species is poorly documented and has yet to find significant popularity in the aquarium hobby. It is easily confused with B. blosyrus at first glance as the body patterning of the two is almost identical but can be distinguished by its slightly larger adult size, noticeably shorter jaw profile and some other, mostly internal, meristic characters.
Prior to 2002 the family Badidae inc…

The hill streams in which this fish can be found are generally shaded by the forest canopy and dense marginal vegetation. Substrates are typically composed of boulders, smaller stones, sand or gravel with submerged tree roots around the margins and quieter areas in which fallen branches and leaf litter collect.
Other fish species occurring in the Tunga…

An assortment of undescribed Oreichthys spp. from India, Myanmar and Thailand are currently traded as O. cosuatis. It can be distinguished from other described members of the genus by lacking a black blotch on the caudal peduncle, plus the following combination of characters: 2-3 perforated scales in lateral line; ½6½ between pelvic-fin origin and dorsal midline; presence of dark stripe in centre of anal-fin, forming a triangular blotch in adult individuals; dorsal-fin with whitish tip and broad, black, subdistal margin in the upper portion of the fin; 11-13 rows…

This species has a chaotic taxonomic history with certain issues still to be resolved. While the name P. mahecola was misapplied to members of the genus Dawkinsia for over a century the fish itself has been widely misidentified as the congener P. amphibius (Valenciennes 1842).
Its identity was partially resolved by Pethiyagoda and Kottelat (2005b) who demonstrated that though valid P. mahecola is not a Dawkinsia spp. but rather a smaller, relatively plain species with a single dark blotc…

This species is uncommon in the aquarium trade which is a little surprising given its huge natural range. Different populations can vary in colour pattern to an extent though all share the defining aspects given by Hamilton, comprising a diffuse yellow-golden marking on the operculum plus a dark spot on the caudal peduncle. The latter is usually surrounded by a variably-sized golden-yellow margin, and the dorsal-fin often contains irregular dark spots and streaks, these sometimes forming a longitudinal band.

This species is confused with P. ticto in much of the available literature and is sometimes listed as a synonym of it. Although some populations of the two species possess a similar colour pattern (there are reports of a P. ticto variant from the south of West Bengal state in India with a red, black-flecked dorsal-fin, for example) they do not occur in the same waters in nature and can be distinguished by examining the lateral line. This is complete in…

D. assimilis has been misidentified as Puntius mahecola (Valenciennes 1844) in the past but the identity of both species was resolved by Pethioyagoda and Kottelat (2005 a, 2005b). They inspected the syntypes of P. mahecola and concluded that though valid it isn’t closely related to any Dawkinsia (then the Puntius filamentosus group) but is rather a smaller, silvery fish with a single dark blotch on the caudal peduncle, located entirely posterior to the anal-fin. It’s wi….

D. exclamatio should also have a sub-terminal mouth and lack dorsal-fin filaments but some specimens possess a terminal mouth and/or possess dorsal filaments, and one specimen also had black caudal-fin tips as typically seen in D. filamentosa, whereas the description states that the fin tips are only dusky and lack distinctive markings.

In P. phutonio the flank markings comprise two black, vertically-orientated blotches, one posterior to the operculum and the other on the caudal peduncle, and within the P. conchonius group this patterning is shared with P. bandula, P. cumingii, P. didi, P. meingangbii, P. padamya, and P. tiantian.
It can be told apart from these by the following combination of characters: smaller adult size of 25 – 30 mm vs. at least 35 – 40 mm; minute maxillary barbels; incomplete lateral line with ab…

This species is widely referred to and traded as the congener ‘Puntius‘ narayani (Hora, 1937). The precise identity of the latter is in doubt, however, plus P. setnai possesses a serrated dorsal-fin spine whereas ‘P.‘
It was formerly included in the Puntius conchonius ‘group’ of closely-related species alongside P. ater, P. bandula, P. conchonius, P. cumingii, P. erythromycter,…
